Proform Parts GM 1-Wire Alternator V-Belt Black Crinkle

The Proform Parts GM 1-wire alternator line is a 12-volt replacement and upgrade charging solution built on the GM 10SI-style case. It has a V-belt pulley and a black crinkle finish. The simple one-wire hookup and internal voltage regulator make it a popular choice for street rods, restorations, muscle cars and custom builds. It also suits any project that needs a cleaner, simpler charging system.

Key Features:

• GM 10SI-style case: a familiar, proven alternator design with an aluminum housing.
• 1-wire hookup: simplified wiring with an internal regulator, so no external regulator is needed.
• V-belt pulley: a machined single V-belt pulley is included.
• Black crinkle finish: a durable, textured finish that looks good in an engine bay.
